214 Evans: NOTES ON GENUS HERBERTA 
may not be present on every individual leaf. Nevertheless, if a 
series of leaves is examined, the majority will show the basal 
teeth clearly. Some of the teeth consist of single cells, but most 
of them are three to ten cells long and often two to four cells wide 
at the base. Occasionally an even larger, lobe-like tooth is 
present. Although the basal teeth are almost always marginal 
it is sometimes possible to demonstrate a surface tooth.

Yellowish or brownish green, sometimes tinged with red or 
purple, often somewhat glossy, growing in more or less extensive 
mats or in pendent tufts, sometimes mixed with other bryophytes: 
secondary stems erect, ascending or pendulous, rigid, mostly 5-10 
cm. long but sometimes shorter, about 0.25 mm. (or fourteen cells) 
wide and 0.2 mm. (or twelve cells) thick, the cells everywhere with 
thickened walls, although showing a fairly marked difference 
between cortical and median regions: leaves imbricated, strongly 
secund, unsymmetrical, narrowly ovate, mostly 1.2-1.5 mm. long 
borne in an interrupted series in the upper part of a stem, more 
rarely on a lateral or ventral branch; bracts and bracteoles mostly 
in four to six series, similar to the leaves but with straighter and 
less divergent divisions and a broad basal pocket, about 1 mm. long 
and 0.45 mm. wide, margin subentire to sparingly and irregularly 
denticulate; antheridia mostly two or three in each axil: female 
inflorescence apparently always terminal on a stem, often with
